Thanks Buddy! I appreciate the verification!

Unraid newbie, who backed himself into a capacity corner pretty early on, and is trying to work out the best way out! I have a TerraMaster F8 SSD Plus, great bit of kit for my use I think (don't need that much storage, but want it fast and quiet), especially once I ditched TOS for Unraid. I have a ZFS Pool of 3 x 2TB M.2 Drives in raidz1, so a little under 4TB usable (no array). I've got about 10 docker containers running from the same pool, and a USB attached external 8TB HDD in assigned maintaining backup of my media folders via Rsync. Dockers are backed up with Appdata Backup plug-in to the same 8TB HDD. I'm ditching an older iMac which was my main screen/plex server and only had 2TB of storage, so 3 x 2TB drives gave me parity, and some extra speed via striping, seemed like enough at the time, and the F8 has 8 M.2 slots, so lots of room to grow. This went very well, and then I started ripping the rest of my DVD/Blu-Ray collection. Next thing I knew, I'm at 76% utilised, and as I understand it, bad things happen when you get over 80% utilised on ZFS... So I need to add drives. Sadly OpenZFS 2.3's not likely to ride in fast enough to solve this for me. I need to erase and rebuild my pool (don't want to drop in 3 more drives for another vdev and lose another to parity, prefer to just increase my raidz1. I figure I should approach it as below: looking for some guidance on if this is the right approach or I'm missing something that will screw me over in the process.... 1. Run backups to 8TB HDD, ensure all up to date. 2. Shutdown NAS, open and install new M.2 drives. Put back together and power back up. 3. Verify the new drives are available (is it worth running pre-clear on them?) 4. Shut down all docker containers. 5. Stop Array - Erase Pool 6. Build new pool in raidz1 with all drives (do I need to pre-clear the original 3 x 2TB M.2's, or can I just allocate them to the new pool?) 7. Restore Appdata backups, start up and verify some containers (not Plex/Sonaar etc that rely on media folders) confirm they're working. 8. Copy back all my media folders. 9. Start up Plex/Sonaar containers and verify. My thinking is that since config runs in RAM, by doing this all while running, I don't need to reinstall my dockers, I can just shut them down and restart once the pool is rebuilt and all app data is back in place? All seems straightforward enough in my head, but I've never done anything like this before, so any suggestions or confidence building confirmations that the above approach is correct would be appreciated!
